Need to ensure sludge concentration certain in reative cell 110, if sludge concentration is too high, just can be from sludge bucket or reative cell 110
Middle unnecessary sludge to be drained into outside tank body 100 by sludge discharge pipe 600, sludge pump 610 can be connect on sludge discharge pipe 600 to be used for
Discharge sludge, thus, it is possible to ensure the normal operation of denitrification process.
Alternatively, tank body 100 also includes the carbon source plus entrance 120 for adding carbon source into reative cell 110.Specifically,
As shown in figure 1, it can be that the opening that is separately provided, or waste water inlet 111 are used as on tank body 100 that carbon source adds entrance 120
Carbon source adds entrance, or while has embodiment shown in the drawings.Thus, when carbon source is lacked in waste water, additional carbon can be thrown
Add on water inlet pipe or directly add to tank body 100, nitrate nitrogen is reduced into into nitrogen as reducing agent.
According to one embodiment of the present utility model, denitrification device 1 is also included for into degassing precipitate and separate device 300
Gas is blowed in case anti-avulsion gas precipitate and separate device 300 is by the scavenging conduit 700 of sludge blockage.
